Description copied from class: SimpleLexer

adds a mapping from a regular expression to the given token code. No provisions are taken to detect conflicting regular expressions, i.e. regular expressions with common matches. To define a specific keyword, e.g. package and also a general identifier, e.g. [a-z]+, make sure to call addToken first for the more specific token. Otherwise it will never be matched.
